We are planning on fully supporting countdowns for all major religious holidays/events.
For some religions, we also need to request the users current location so that we can correctly countdown to sunset/sunrise for the start of the event. This is the only reason you’ll see mostly Christian Holidays on the site, as they do not have this requirement.Anonymous commented
I agree that Jewish holidays are important. If you're going to have Christian, then represent other religious holidays or drop it and stay with seasons.
